. Velma made her own Faraday cage for £300 that she claims filters out pulsed electro-magnetic waves
. Says she suffers agonising head and nerve pain, memory loss, tinnitus, ectopic heart beats, vertigo and aching joints if she goes near mobile phones, WiFi and satnavs
. Electrosensitivity is a controversial condition. HPA say there is no scientific evidence linking ill health with electrical equipment

She suffers from electromagnetic hypersensitivity intolerance syndrome (EHS) which means she cannot stand to be near pulsed electromagnetic fields.
Velma’s condition emerged with the arrival of 3G mobile phones, although she says a previous electric shock as a teenager may have made her more susceptible.

Velma, who has been unable to work since suffering from RSI and a compressed nerve on her spine, suffers agonising head and nerve pain, memory loss, tinnitus, ectopic heart beats, vertigo and aching joints if she goes near mobile phones, WIFI and satnav.

She is forced to spend much of each day in a makeshift Faraday cage in her flat in London. However, in the summer she takes the opportunity to escape to a park as she says this helps to earth her system.

Velma made the Faraday cage herself from off-cut material costing £300. A ready-made version would have cost her £800.

She claims metal fibres in the netting shield her from the microwave signals and stop her from suffering EHS symptoms.

She said: 'I can’t do anything that normal people do, like eating, reading, writing, studying, whilst being exposed to microwave signals without experiencing symptoms. It’s made my life a living hell.

Velma worked as a secretary for a number of firms in the 1980s.

She said: 'Even back then I could feel a huge agitation when using the computer, but I thought it was just because I didn’t have the technological skills.

'Now I wonder if I was starting to experience the early symptoms of ES Electrosensitivity.

'I am studying at home whilst also undertaking training to become a Sound Therapist.

'I'm also looking to undertake a doctorate as I need to keep my brain active and I'm unable to work in a work or college environment.

'My friends are very supportive but there’s only so much time you can spend with the woman that can’t go anywhere or do anything.

'I used to love going to festivals and experiencing live music, but because everyone has a mobile I can’t even go near a gig now due to mobiles close to my head.

'The last gig I went to was Radiohead. I knew I was getting worse and wouldn’t be able to go to any more so I wanted to make it a good one.

'It’s so sad that I can no longer do the things I enjoy.'

Electrical Sensitivity, also known as Electromagnetic Hypersensitivity Intolerance Syndrome, is a controversial condition that is recognised in Spain and Sweden but not in the UK.

Velma said: 'I’ve been to my GP countless times begging for tests, but GPs won't instigate the environmental tests needed. One neurological expert said there are people worse off than me and wouldn't help me. It is so frustrating that medicine isn’t keeping up with the technology.

'We desperately need a white zone - an area where there are low or no emissions - where we can go to relax and recuperate and detox.'
